application filed Hay 16, 1912. Serial No. 697 .623.

Beit known that i, PAUL Genauer., a citi- .Zen of the German Empire, residing at Ben linlyvihnersdori', in the Kingdom of Prussia, .Gernian have invented certain nevvvand useful@Improvements in Automatic Guns; andi do -hereby declare the followingio be`"a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to Which' it appert'ains tomalre Aand use the same.

My invention relates to improvements in iutom'atic guns, ,and more particularly to the mechanism orejecting the empty cartridge case. in guns.;ofthis class the empty cartridge case remains within the ejecting trib-e or oriiice, until another one is inserted, /and pushes `the rstA one out of the tube. When unloadin the gun it may happen, that the lirst un red cartridge located Within the ejecting tube isii'red.

The object o the improvements is to conn struct the ej'ec'tingmcchanism in such a Way, that. this obje'ctireiA is removed. ALnd With this object-in viewfpiny invention consists in constructing the ej'ecting mechanism in such a Way, that thev cartridge or empty cartridge case to be jectedfhsafely ejected even when the ire arm ishdiiiected upward.

Forf-thepurpose of explaining the invention Aexample embodying the same has beenfshoirn in the accompanying drawing, in 'ivhichfthe same letters of reference have "been-.used in all the views to indicate correspending-parts.

lnf.,s'aid drawings Figure l, is a longitudivnal sectin of the breech end oi the barrel, the ejecting tube, and a part of the cartridge carrier, and Fig. 2, is a similar section-showing the cartridges in dierent positions.

For the purpose of explaining the invention l have shown the same embodied in an automatic gunv of the Maxim type. But I Wish it to be' understood, that my invention may also be embodied' in guns of a dierent type, and that various changes may be made 1n the arrangement and construction of the parts shown in the iigures.

Referring to thefigures, the letters a and b indicate two successive cartridges or cartridge cases, c is the. cartridge carrier, Il the ejecting orifice or tube, and the supporting spring which in the proper posi' tion of the cartridge carrier thrusts the cartridge Within the ejer-ting tube forvvard.-

lhese parts are known in guns of the type indicated and need no detailed description.

Referring nov.Y toy those parts to which my invention more particularly relates, .l provide a pawl e oparticular form, which 1s pivotally mounted at the bottom side of the ejecting tube d on a pin or shaft f, and is held in the position shown in Fig. 2 by a small spring Z. As shown th'e said pawl 1s formed at its rear end with a nose k Which is adapted to be pressed by the spring against the cartridge a 'at a point near the bottom of the latter. Above the pivot the pawl is formed with a projection g. When an empty cartridge case is being inserted the pavvl e is depressed with its nose L* against the action of the spring Z: Now the cartridge case is supported by the pawl at two points, viz. on the nose ic and the projection g. Thereby it is securely held in position. After bei/ng released by the car tridge carrier the'cartridge case is pushed forward by the spring h, so as to slide beyond the nose Ic and, after the pawl has been rocked upward, beyond the projection g and out of the ejector tube. Evenin an inclined position of the arm there is no possibility or a cartridge case to remain Within the ejector ltube or to fall back into the breech block casing of the gun.

I claimherein' as my invention:

1. In an automatic gun, an ejector tube, means adapted to move'a cartridgegor cartridge case into the same, a pair of connected movable projections extending transversely into said tube for supporting said cartridge means adapted to move a cartridge or car-v tridge case into the-same, a member pivota-lly mounted on said ejector tube, a nose on said member extending transversely into said tube and arranged to engage and be moved in one direction by Asaid cartridge or cartridge case to swing said member on its pivot, a projection on said member at a distance from said nose extending into said tube and arranged to'engage said cartridge or cartridge casing and to be actuated in the are oit a circle toward the inlet end of said tube as the saidrmember is swung, means for moving.;` said cartridge or eartridge case beyond said nose and relatively to said projection and. means for moving said member' to snap said nose behind said cartridge or cartridge case and to actuate said projection in the arcot a circle toward the exit end of said tube whereby said cartridge or cartridge case is impelled and tilted do\\n\\'ardly toward said eXit end of the ejector tube.

3. in an automatic gun, an ejector tube, means adapted to move a cartridge or cartridge case into the Same, a member pivotally mounted on said ejector tube, a nose at the free end of said member extending transversely into said tube approximately at the inlet end thereof and arranged to engage and be moved in one direction by Said cartridge or cartridge case to swing said member on its pivot, a projection on said member adjacent to its pivot extending into saidtube andv arranged to engage said cartridge or cartridge case and to be actuated in the arc of a circle toward the inlet end of said tube as the said member is swung, a Spring or'moving said cartridge or cartridge case beyond said nose and relatively to said projection and a spring 4:' r moving said member to snap said nose beyhind said cartridge or cartridge case and to aetuate said projection 1n the arcof a circle' toward the exit end of said ejector tube whereby said cartridge or cartridge ease is impelled and tilted downwardly toward said j exit end of the ejector tube.
